DOOR-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 596,050, dated December28, 1897.

Application filed February 4, 1897. fierlal No. 621,941. (No model.)

T at whom it may concern.-

Be it known that I, EDWARD BYRNES, a citizen of the UnitedStates,residing at New York,

. in the county of New York and State of New York, have invented certainnew and useful Improvements in Door-Fasteners; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to looks, but more particularly to looks orfasteners for doors.

The primary object of the invention is to provide'a lock or fastener fordoors and the like adapted to be operated from either side of the door,so as to effectually lock and hold the same from movement when desiredand to conceal and prevent access from the out side to thefastener-operating mechanism,

thereby permitting the locking mechanism to be operated from the insideat all times, but

preventing a person either tampering with or releasing said mechanismfrom the outside of the door.

A further'object of the invention is to pro vide a simple, efficient,and inexpensive fastener which may be readily applied ,to various formsand constructions of doors and similar devices.

The invention will first be hereinafter more particularly described, andthen pointed out in the, claims at the end of the description.

Referring to the accompanying drawings, forming a part of thisspecification, Figure 1 is an elevation, looking at the inside of adoor, illustrating in full lines the invention in position for fasteningthe door and in dotted lines when released. Fig. 2 is a fragmentaryvertical sectional View, on an enlarged scale, partly in elevation,taken on the line II II of Fig. 1 and illustrating one form of key forrotating the fastener operating spindle or axle andthe means forconcealing the same from the outside of the door. Fig. 3 is a verticalsectional View immediately inside of the spindle or axle handle, showinga portion of the rotating element and the securing or thimble plate.Fig. 4: is a detail side elevation of the spindle, securing-plate, androtating element, illustrating one means for limiting the rotary motionof the spindle; and

- Fig. 5 is a fragmentary front elevation of the door with the means forconcealing the outer end of the spindle in position to permit thefastener to be operated.

In the drawings, A may designate a door of any preferred form suitablyarranged in the door-case by hinging or otherwise and provided upon itsinner side with a securing or thimble plate 19, secured thereto byscrews or in any suitable manner and having aprojecting tubular boss orthimble 1), adapted to fit in a transverse aperture in the door. Aspindle or axle B may be journaled in the securingplate b, so as toextend through the aperture in the door, and may have its inner endprovided with a suitable handle, as at 17 secured to or formedintegrally therewith, and its outer end with a polygonal orotherwise-formed end adapted to be engaged by a suitable key, as at bFig. 2, so that said spin- 'dle may be rotated either from the inside orthe outside of the door. The spindle may be rotatably held to thesecuring-plate by a cylindrical nut, as at 19 arranged on ascrew-threaded portion of said spindle and keyed or suitably securedthereto, a thimble, as at 19 fitting the aperture of the" door andabutting against the outer surface of said nut, being provided, whendesired, to serve as a bearing-surface for the key 12 The spindle or theshank of the handle I), as the case may be, may have a portion thereofof a polygonal form, upon which may be arranged an element or casting 0,so as to rotate therewith, said element or casting being preferablyprovided with a recessed portion in which a projection c on the plate I)is adapted to work or slide, so as to engage the sides of said recessedportion to limit the movement of the spindle B to a partial rotation.The casting may have one or more arms 0, in this case three, forming asubstantially T-shaped body with the arms extending in differentdirections, though in some instances apertures or other securing meansmay be employed. These arms may be radially arranged with respect to thespindle and may have their outer ends pivoted to links oihaving theirouter ends pivoted to the inner ends of bolts 0 so as to cause saidbolts to be drawn toward or forced from the spindle when the latter isrotated. A guide or guides, as at 0 provided with suitable eyes may besecured to the door, in which the bolts may slide, and a catch orlocking-plate, as at c, similarly formed to said guides may be arrangedin the path of movement of each bolt, so as to engage the outer endthereof, said bolts as arranged being in substantially the same plane asthe arms of the casting while engaging the catches, so as to form adead-center therewith, but which may be readily withdrawn from thecatches through the links 0 and arms 0 of the casting by rotating thespindle B. By this means a simple and powerful fastening device isprovided which may be readily operated from either side of the door.

For the purpose of concealing or preventing tampering with the fasteningmechanism from the outside of the door I may arrange a hasp or hingedplate D on the outside of the door above the outer end of the spindle,so as to have the free end of the pivoted or hinged member swing acrossthe face or outer end of said spindle to conceal it from view. The freeend of the hinged member may have a slot adapted to fit over a staple,as at d, and when thus engaged a padlock, as at (1, may have its shacklepassed through the staple, so as to rigidly hold the swinging member ofthe hasp over the outer end of the spindle B, though of course anysuitable means maybe employed to prevent tampering with theoperatingspindle, and the hasp and lock may in some instances bedispensed with and a rosette or escutchcon-plate similar to that used onnight-latches employed, if desired.

In some instances it is desirable to inform an occupant of the house orother person when the locking-bolts have been released, and for thispurpose I may provide a suitable alarmas, for instance, a gong-as at E,Fig. 1, having, preferably, a flexible connection with thebolt-operating mechanism. A plate, as at 6, maybe secured to one of thebolts where it is pivoted to one of the links, to which a cord e orother flexible connection maybe secured, and to the gong, so that whenthe bolts are released the gong will be sounded, and when bolted orcaused to engage the catches c said connection will yield or be takenup, so as not to sound the alarm.

The construction and operation of the invention will be readilyunderstood from the foregoing description, taken in connection with theaccompanying drawings.

Assuming the parts to be in the position shown in full lines, it will beseen that the spindle or axle B may be rotated either by the handle 11from the inside or by the key I) from the outside of the door, so as tothrow the casting G, the links 0 and the bolts 6 to the releasedposition or that shown in dotted lines, or to the fastened or lockedposition by rotating the spindle in the opposite direction, theprojection c, engaging the sides of the recessed portion of the casting,serving to limit the rotary motion of the spindle. By forcing thepivoted member of the hasp over the end of the staple d and securing thepadlock in position after the bolts 0 engage the catches a the door willbe securely fastened and tampering with the operating-spindle B from theoutside of the door avoided.

I thus provide simple and efficient means whereby the door may be boltedor fastened from either side thereof and the means for operating thefastening mechanism effectually concealed to prevent tampering or thepossible operation thereof from the outside.

The end of the spindle which the key is adapted to fit may be variouslyformed, so that no two keys will be exactly alike, and keys. may be madeto fit variously-formed apertures in the spindle instead of engaging itsouter surface.

It is obvious that the bolts may be of any desired number and variouslyarranged to suit difierent constructions of doors, that where the worddoor is employed it is intended to include devices operating in asimilar manner, and that some of the parts may be dispensed with orothers substituted therefor without departing from the spirit of myinvention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. In a door-securing mechanism, the combination of a flanged tubularbearing secured in an opening made through the door and having aprojection, an operating-spindle journaled in said bearing andprojecting therefrom on one side of the door where it has a suitablehandle for turning purposes, a plate fastened on said spindle adjacentto the tubular beairng and having an arc-shaped recess receiving theprojection on the latter whereby the oscillations of the spindle arelimited, and locking-bolts operatively connected with said plate,substantially as described.

2. In a door-securing mechanism, the combination with the door having anopening extending transvcrselythrough it; of a flanged tubular bearingengaging said opening with its flange extending on the inner side of thedoor and secured thereto; a spindle engaging said tubular bearing andprojectingon the inner side of the door where it has an operating-handleand exposed at the outer side of the door without projecting therefrom,this outer end of the spindle being formed for rotative engagementtherewith of a key, and said spindle having a screw-threaded portion; anut engaging the said screw-threaded portion and bearing against theinner end of the tubular bearing to prevent inward movement of thespindle; one or more locking-bolts on ing said tubular bearing andprojecting on the inner side of the door where it has anopcrating-handle and exposed at the outer side of the door Withoutprojecting therefrom, this outer end of the spindle being formed forrotative engagement therewith of a key, and said spindle having ascrew-threaded portion a nut engaging the said'screw-threaded portionand bearing against the inner end of the tubular bearing to preventinward movement of the spindle; a thimble in the door-openingconstituting a bushing for the same between the said nut and the outerend of the opening; one or more locking-bolts on the inner side of thedoor; and eccentric connections between the same and the spindle.

In testimony whereof I affix my signature in presence of two witnesses.
